Male Reproductive System Overview

Male Reproductive System

• The male reproductive system's primary function is to produce and deliver sperm for fertilization.
• Key organs include the testes, epididymis, vas deferens, ejaculatory ducts, urethra, and penis.
• Testes: Located outside the body in the scrotum. Produce sperm and testosterone.
• Epididymis: A coiled tube where sperm mature and gain motility.
• Vas deferens: A tube that carries sperm from the epididymis to the ejaculatory duct.
• Ejaculatory ducts: Combine with the seminal vesicles to form a passage for sperm and fluids to the urethra.
• Seminal vesicles: Produce seminal fluid, a component that provides nutrients and facilitates sperm movement.
• Prostate gland: Secretes a fluid that nourishes and protects sperm.
• Bulbourethral glands: Secrete a mucus-like fluid to lubricate the urethra prior to ejaculation.
• Spermatogenesis: The process of sperm production. Occurs within the seminiferous tubules in the testes.
• Testosterone: The primary male sex hormone, crucial for the development and maintenance of male secondary sexual characteristics.

Female Reproductive System

• The female reproductive system is responsible for producing eggs (ova), supporting a developing fetus, and supporting childbirth.
• Key organs include the ovaries, fallopian tubes (oviducts), uterus, cervix, and vagina.
• Ovaries: Produce eggs (ova) and the hormones estrogen and progesterone.
• Fallopian tubes (oviducts): Where fertilization typically occurs.
• Uterus: A hollow muscular organ where a fertilized egg implants and develops into a fetus.
• Endometrium: The inner lining of the uterus, which thickens in preparation for implantation and is shed during menstruation if no implantation occurs.
• Cervix: The lower part of the uterus that connects to the vagina.
• Vagina: The muscular canal that receives the penis during sexual intercourse and is the birth canal.
• Ovulation: The release of a mature egg from an ovary.
• Menstrual cycle: A cyclical series of changes in the uterus, ovaries, and hormones that prepares the body for pregnancy.
• Oogenesis: The process of egg production. Starts prenatal, but maturation and release occur cyclically.
• Estrogen and Progesterone: Crucial female sex hormones, regulating the menstrual cycle, development of secondary sexual characteristics and supporting pregnancy.

Interactions between Systems

• Sperm and egg unite in the fallopian tubes.
• Fertilized egg implants in the endometrium.
• Hormones act as messengers between the two systems, coordinating the reproductive process.
• The systems are interdependent in maintaining reproductive health.
